Information management

The WMO Information System (WIS) is the pillar of the WMO strategy for managing and moving weather, water and climate information in the 21st century. WIS provides an integrated approach suitable for all WMO Programmes to meet the requirements for routine collection and automated dissemination of observed data and products, as well as data discovery, access and retrieval services for all weather, climate, water and related data produced by centres and Member countries in the framework of any WMO Programme.

WIS is being designed to dramatically extend WMO Members' ability to collect and disseminate data and products. It will be the core information system utilized by WMO Members, providing linkages for all WMO and supported programmes associated with weather, climate, water, and related natural disasters. It is being built upon the Global Telecommunication System of WMO's World Weather Watch, using standard elements and at a pace feasible for all Members.

WIS encompasses three types of centres. For regional and global connectivity, Global Information System Centres (GISCs) will collect and distribute the information meant for routine global dissemination, while serving as collection and distribution centres in their areas of responsibilities; they provide entry points, through unified portals and comprehensive metadata catalogues, for any request for data held within the WIS. Connected to the GISCs, the Data Collection or Production Centres (DCPCs) will be responsible for the collection or generation of sets of data, forecast products, processed or value-added information, and/or for providing archiving services. National Centres (NCs) will collect and distribute data on a national basis and will coordinate or authorize the use of the WIS by national users, normally under a policy established by the respective permanent representative with WMO.

The WIS implementation builds upon existing WMO information systems in a smooth and evolutionary process, in two parts that are developed in parallel:

Part A: the continued consolidation and further improvement of the WMO Global Telecommunication System for time- and operation-critical data to meet operational requirements of WMO Programmes in addition to the World Weather Watch. It is implemented essentially through dedicated telecommunication means (leased links, data networks, satellite-based telecommunications) providing a guaranteed quality of service;

Part B: an extension of the information services through flexible data discovery, access and retrieval services to authorized users, as well as flexible timely delivery services. It will be implemented essentially through the Internet.

The WMO data representation formats, i.e. table-driven code forms, will be used for real-time exchange of operational critical data, but the user will be able to select from a wide variety of optional data representation formats.

The WIS is implemented and operated by WMO Member countries.

As part of the WWW activities, an Operational Information Service (OIS) is available, whose objective is to collect from, and distribute to, WMO Members and WWW centres detailed and up-to-date information on facilities, services and products made available in the day-to-day operation of the WWW, including monitoring analysis of operations.
